September 5th, 2012Windows PowerShell 3.0:
· Windows PowerShell Workflow lets IT Pros and developers apply the benefits of workflows to the automation capabilities of Windows PowerShell. Workflows allow administrators to run long-running tasks (which can be made repeatable, frequent, parallelizable, interruptible, or restart-able) that can affect multiple managed computers or devices at the same time.
· PowerShell sessions can be disconnected from the remote computer and reconnected later from the same computer or a different computer without losing state or causing running commands to fail.
Robust Session Connectivity:
· Remote sessions are resilient to network failures and will attempt to reconnect for several minutes. If connectivity cannot be reestablished, the session will automatically disconnect itself so that it can be reconnected when network connectivity is restored.
· Scheduled jobs that run regularly or in response to an event.
· Commands that can be executed with a delegated set of credentials so users with limited permissions can run critical jobs
Simplified Language Syntax:
· Simplified language syntax that make commands and scripts look a lot less like code and a lot more like natural language.
· Improved cmdlet discovery and automatic module loading that make it easier to find and run any of the cmdlets installed on your computer.
· Show-Command, a cmdlet and ISE Add-On that helps users find the right cmdlet, view its parameters in a dialog box, and run it.
A new provider development model:
· This new model brings down the cost of provider development and removes the dependency on COM.
A new MI Client API to perform standard CIM operations:
· The API can be used to interact with any standard WsMan + CIMOM implementation, allowing management applications on Windows to manage non-Windows computers.
The ability to write Windows PowerShell cmdlets in native code:
· The new WMI Provider APIs supports an extended Windows PowerShell semantics API allowing you to provide rich Windows PowerShell semantics. e.g., Verbose, Error, Warning, WhatIf, Confirm, Progress
Connections are more robust:
· Remote connections communicating over WinRM are more robust to transient network failures such as a flaky WAN connection. In the case of a complete network failure, connections are gracefully disconnected and can be reconnected when network connectivity is restored.
Remoting is more Standards-compliant:
· Standard WS-Management operations, including Create and Delete, can be performed over WMI. Remoting for cmdlets written in native code using the new WMI provider development model uses WS-Management instead of DCOM.
Multiple PowerShell sessions can be shared in the same process:
· PowerShell sessions from the same user to the same session configuration (WinRM plug-in) can run in a single shared process instead of separate processes. This improves scalability and performance by allowing multiple sessions to share memory and other server resources.
Management OData IIS Extensions:
· Management OData IIS Extension enables an administrator to expose a set of PowerShell cmdlets as a RESTful web endpoint accessible via the Open Data Protocol (OData). This enables Windows and non-Windows clients to discover and invoke PowerShell cmdlets remotely over standard web protocols and interfaces.
Server Manager CIM Provider:
· The Server Manager CIM Provider packaged with Windows Management Framework 3.0 allows you to manage your Windows Server 2008 R2 SP1 and Windows Server 2008 SP2 servers from Server Manager in Windows Server 2012 or Remote Server Administration Tools for Windows 8.
December 5th, 2011Customer Reported Bug Fixes:
· Many customer reported bugs have been fixed since the WMF 3.0 CTP1. The release notes contains a list of bug titles, but please check Connect for full details.
Single Command Pane in Windows PowerShell ISE:
· The Command and Output panes in Windows PowerShell ISE have been combined into a single Command pane that looks and behaves like the Windows PowerShell console.
· The WMF 3.0 CTP1 release notes described a new Updatable Help system in Windows PowerShell 3.0 and included a copy of the help content. The Updatable Help system is now active on the Internet. To download and update help files, type: Update-Help.
Windows PowerShell Workflows:
· A number of enhancements have been made in the scripting experience for Windows PowerShell Workflows, including new keywords: Parallel, Sequence & Inlinescript. A document describing these changes will be published to this page shortly.
· The Get-Module cmdlet now supports implicit remoting. You can now use the new PSSession and CIMSession parameters of the Get-Module cmdlet to get the modules in any remote session or CIM session. A number of other module enhancements are listed in the release notes.
